The reasons for all this spying? "Terrorism" and "Espionage" - you know, the same threats we've faced for that entire graph. But now we apparently need to spy on two or three times as many people to combat them. Yeah, right. Again, its hard to escape the conclusion that the "oversight" on these warrants is simply a rubberstamp and that the threshold for granting one has dropped significantly in the past few years. And if we want to change this, we're just going to have to get a new government.
